    摘要: Disclosed herein is a distal end electrode assembly for use in connection with electrosurgical devices, particularly those adapted for the modification, sculpting, resection, removal, or vaporization of tissue, configured for coagulation, cauterization or hemostasis purposes, or utilized for thermal treatment of normal and tumorous tissues. In the context of the present invention, mechanical fastening means, epoxies and other high-temperature adhesives connecting electrode(s) to insulator(s) are replaced with brazed joints to yield electrosurgical devices capable of safely and reliably operating at high power densities and elevated temperatures without thermal failure of the bonds between the electrode and the insulator. The use of brazed joints further permits the construction of miniaturized, compact electrosurgical devices, of both monopolar and bipolar configurations, having utility in a number of divergent fields, from arthroscopy to otolaryngology to oncology, and applicable to both laparoscopic and open surgery techniques. Thus, active electrodes and electrosurgical devices of the present invention maximize efficiency, safety and reliability while minimizing manufacturing cost and device profile.

    摘要: An electrosurgical instrument, system and methods are provided for the vaporization, cutting, coagulation, or treatment of tissue in the presence of an electrically conductive fluid medium. The electrosurgical probe comprises at least one active electrode, and at least one “floating” electrode having at least one end in close proximity to at least one active electrode. The floating electrode is not connected in any way to the electrosurgical power supply, but rather has a “floating” potential determined by the shape and position of the electrode. The floating electrode increases current density in the region of the probe distal end.

    摘要: Herein disclosed are dual-mode electrosurgical devices designed to function in a first mode in which high-density RF energy is used to cut or vaporize tissue, and then a second mode in which lower-density RF energy desiccates tissue to produce hemostasis, as well as methods of performing electrosurgery using same. Devices formed in accordance with the principles of this invention may be used for any surgical procedure in which highly vascular tissue is cut electrosurgically in a dry or semi-dry field, examples of which include tonsillectomy, liver resection, and cosmetic procedures such as breast augmentation, breast reduction, breast mastopexy, and abdominoplasty.
